This invention' has general` reference to kerosene burners for melting furnaces,steam generators and steam and hot-Waterheaters, &c and it consists, essentially, in the novel and peculiar combination of parts and details of construction as hereinafter rst fully sqt-.-

forth anddescribed'and then pointed out'in the claims.

In the drawingsalreadyreferred to, which serve to illustrate this invention more fully,

carbone 4is the fuehenfployed for producing the necessaryheat.. To attain this objectl I' construct .this burnerpfa tube or body, -A,. having atits upper edge a' laterally'projecting flange2, bymeansfofwhicn and-.suitable bolts 3, this bodyis/secured. to the base-platey 4 of a furnace B, of any desirable construe# tion. This body A is perforated in its' Walls by a' series of apertures 5,"through which air L fis admitted tothe interior of-said body and sustain combustion.

thereby to supply ltube 15 intothis funneland their the 4necessary oxygen to 4 i cible E is employed .to `contain themetal, I l

-t one side and near the lower end' of the tube A -there are formed,` and fprojecting'- therefrom, hinge-lugs 6, WhichA engage Similar'hingelugs on a reetangularpan-C, as 'sOV- clearly indicatedin Figa. 6 and- 7, pintlesf in said ge-lugsjand facilitating theswingin of saidan@ von its hinge-lugs. y On the side' of the tu e Aioppositeto that Where .v

thehinfgolugs 6 arelocated, there is formed 65 a projecting lug 9, WhereWith engages a. spring-catch l0, which catch is 'bolted' to the pan 'C by'a screw 12, so as to retain the pan C, normally, vin al horizontal'position. Byl

This fuel-is contained suitable tank D,.located any- 8'0 Where above the level of the pan C'andiitted With-a filler plug v13, Fig. 1, and, ifdesired, with a' liquid indicating-tube Orfeo-called Vglass-gage 1 4. .From this tank D. leads a tube 15, which conducts the liquid fuelfromj 85. the tank D into the tube A, a stopvalve.16, being provided to regulate the flow of liquid uel.

v Inorder to ascertain the amount of fuel supplied to the burner, I -providein the suglift e ply-tube a break or gap and lit. the end o supply-'tube 17 yWithafunnel7 18,' so thatl drops of the liquid fuel' 19, 'assho'wnin Fig.;

4, may be observed .tofall from the supplyfrequency 9 5 regulated by the stop-valve 16.` J The liquid fuel supply-tube '1f-' enters the burner-tube A at its--side and it isdovvn- Wardlybent. therein so asl todischarge; the

liquid into, approximately the centerv of, thef 100` panCQ `When this' fuel has heated the end ofthe supply-tube V17v and the tube "A, the

vliquid-fuel be heated as it enters the burner-tube 'A- and being'fin part, evapo rated and'. converted into gas Will produce 105 Athe intense heat vrequired for melting fun4 I nace'sl andisteam generators, &c.', a number of these burners and appliances being fitted up, When'necessary, to afford the required amount of heat.

In metal-melting-furnaces, Where a cruform therein a passage, 20, which is a continuation of the tube A, said passage 2O being flared to assume the size of the interior 21 of said furnace, and in order to pro- 25, 26, and furnish it with pivots 27, whichrevolve in bearings at the upper end of said standards. The standard 25 has also a projecting stud 28, upon which is mounted a hand-wheel 29, and a pinion 30, the latter meshing with` a spur-wheel 31 secured to one of the trunnions or pivots 27. By revolving this hand-wheel 29 the furnace B is tiltedin an obvious manner.

In Figs. 2, 6, and 7, I have shown the burner-tube A as being rectangular in transverse section, and the pan C similarly shaped, while in the remaining figures of the drawings these parts are assumed to be circular in cross section, and I have shown the pan as being considerablylarger than the transverse dimensions of said tube A. It is obvious that the contour of the cross section of the burnertubeAis non-essential, as long as the pan below the tube projects therefrom a sufficient distance that the ilaine of the burning liquid fuel may impinge upon the outer surfaces of said burner tube to assist in the initially heating of the same to 4provide for the thorough conversion of the liquid fuel into the gaseous state. Having thus fully described this invention I claim as new and desire to secure to me by Letters Patentv of the United States- 1. As an iin roved article of manufacture, a burner for urnaces consisting of a perforated tube having an outwardiy-projecting flange at its upper end; hinge-lugs on one side of said tube, and a projecting lug at the o posite side thereof; a pan. below said tube, t ere being hinge-lugs in said pan adapted to engage thehinge-lugs on vsaid tube; pintles in said hinge-lugs', and a catch on said pan adapted to engage the lug on said tube, as stated.

2. The combination, with a tank, of a supply-pipe leading therefrom; a stop-valve in said supply-pipe; a further supp v-pipe,

,being a. continuation of the first-mentioned supply-pi e; afunnel at the end o f said supply-pipe elow said stop-valve; a furnace; a urner 1n said furnace comprising` a perforated tube; a base-plate in said furnace tol which said burner-tube is attached; a pan below said burner-tube, said pan being larger than the transverse dimensions of said tube;

means for hinging said pan to said burnertube, and further means for locking said pan to said burner-tube, the supply-pipe entering the vertically-disposed burner-tube at its ,side and having its end downwardly bent to discharge the liquid fuel approximately in the center of said an.

3. In a kerosene urner, a perforated tube, a supplyipe in said tube; a pan below said tube and inged thereto, a combustion chaml ber above said tube having a flared passage and projections in said passage, as stated.

In testimony that I claim the foregoing as my invention I have hereunto set my hand in the presence of two subscribing witnesses.
